A receiver receives a data packet with a header and a payload. The payload includes at least one full service data unit, one or two service data unit fragments, or at least one full service data unit and at least one service data unit fragment, where a service data unit fragment is only located (i) at the beginning of the payload or at the end of the payload or (ii) at the beginning of the payload and at the end of the payload. The header includes a single field consisting of a first bit and a second bit, even when a number of full service data units and service data unit fragments in the payload is more than two, the single field indicating whether (i) the payload begins with a fragment of a service data unit and (ii) the payload ends with a service data unit fragment. Digital signal processing circuitry processes the header to determine processing for the payload.

Provided are a packet transmission method and device and a computer readable storage medium. The packet transmission method includes: receiving, by the routing device, a packet, determining whether the packet is a packet that needs to be accelerated, in response to determining that the packet is the packet that needs to be accelerated, querying a customized connection tracking table to acquire connection tracking information corresponding to the packet, transmitting the packet to a driver layer for processing, where the customized connection tracking table includes connection tracking information of a packet corresponding to a packet type which is predetermined to be accelerated.

A computing system may include a server configured to provide Software as a Service (SaaS) application sessions and at least one client computing device cooperating with the server to run a first one of the SaaS application sessions having a form including an input data field, and generate an application program interface (API) based upon the input data field from the form. The at least one client computing device may further link an output of an Internet of Things (IoT) sensor corresponding to the input data field to the API, and collect data output from the IoT sensor and populate the input data field in the form via the API.

An integrated circuit device may include a configurable packet parser that is programmable to simultaneously process multiple protocols to separate packet headers from payload data of network packets. The separated packet headers and payload data can be stored in respective memories. Replacement packet headers can be generated by a programmable header builder from the separated packet headers according to configurable commands, and new packets can be generated from the replacement packet headers and the payload data.

Maintaining client version affinity during a rolling server cluster upgrade includes a server in the server cluster receiving a request from a client and checking the request for a version cookie indicating a software version that the client is running. Responsive to a determination that the server is running the same software version as the client, the server serves the request. Responsive to a determination that the client is running a software version matching a previous software version of the server, the server initiates a software upgrade on the client instead of servicing the request. Responsive to a determination that the server is not running the same software version as the client, the server forwards the request to one of the other servers in the server cluster that is running the same software version as the client.

Methods, systems, and devices for determining a subset of users from among a set of users based on a set of received information associated with a photograph, where the disposition of the information is used to first determine the subset and then perform facial recognition on the subset of photographs for each user in order to accurately identify each user or users present in the photograph.

Aspects of the disclosed technology address limitations relating to packet replication for multi-destination traffic, by providing methods for performing hardware-based replication in network infrastructure devices, such as switches. In some aspects, application specific integrated circuits (ASICs) resident in physical devices can be used to perform packet replication. Depending on implementation, a hardware-based replication process can include steps for receiving a first packet that includes a first outer header containing first address information, receiving a second packet including a second outer header containing a hardware replication flag, forwarding the first packet to all virtual tunnel endpoints (VTEPs) connected with the TOR switch, and performing hardware replication for the second packet based on the hardware replication flag to generate one or more unicast packets. Systems and machine readable media are also provided.

The present disclosure relates to a method and system for exchanging packets of information pertaining to an instrument. Data pertaining to the instrument is obtained from internal and external sources, which may be governmental or non-governmental. The obtained data undergoes a process of clustering and dimensional reduction to arrive at cleaned and optimised data attributes. A predictive model is built using those data attributes. A testing provision is included in the proposed method and system that allows for validation of the constructed model by using test data and comparing the predictions with actual values. Upon validation, the model predicts one or more packets of information that can have a bearing on the exchange of packets pertaining to the instrument.

A network application program product and a method for processing an application layer protocol are provided. The network application program product includes a network application program executed in a user mode and a packet filtering module executed in a kernel mode. The network application program transmits connection information, associated with network connection to the network application program, to the packet filtering module. The packet filtering module captures a to-be-processed packet on the network connection according to the connection information; analyzes the to-be-processed packet into at least one protocol data unit; compares the protocol data unit with preset code content; and transmits the protocol data unit to the network application program or the data access module according to the comparison result for later processing.

The present invention provides a methods, apparatus and systems for improving a systems-level data rate on a communications link such the orthogonal frequency division multiplexed multiple access (OFDMA) downlink used in used in WiFi and LTE cellular/wireless mobile data applications. The present invention preferably uses a form of multilevel coding and decoding known as tiled-building-block encoding/decoding. With the present invention, different receivers coupled to different parallel downlink channels with different channel qualities decode different received signal constellations at different levels of resolution. This allows the downlink of the OFDMA system to operate with a significantly higher data rate, thus eliminating existing inefficiencies in the downlink and significantly increasing system level bandwidth efficiency.
